broad term for selling products or services using electronic means such as
the Internet, other computer networks, or wireless (mobile) transmissions.
It should not be mistaken for E-Procurement
(which is buying products or services using electronic media) and for
E-Business, that involves both E-Commerce
and E-Procurement. Unfortunately, sometimes the term is also used as a synonym
of E-Business.

Even then, although it is a broad term, it does not
include all processes that can be supported by electronic means, there has
to be a business transaction component in it. For example it does not include:

E-Mail.

E-HRM (using an internet-enabled employee database).

E-Knowledge Management.

E-CRM.

Other internal internet-enabled systems.

Two forms of E-Commerce can be distinguished, being business
to consumer (B2C) and business to business (B2B).
